rlhis invention relates `to lip turning and setting machines. As herein illustrated, the invention is embodied in a machine which is particularly adapted for turning andV setting the lips of double-lipped all-leather welt insoles, although the invention is by no ymeans limited to. such use sinceit is advantageously f i Vsired continuous feed of the work. As illusapplicable to operations upon soles of other types. y

One object of the present invention is to provide an improved lip turning and setting machine which is capable of operating at high Speed but which neverthelesspmay be relied upon to turn the lips ofeasily tearable, flimsy, insole stock without having any appreciable tendency to injurethe'lips,'par ticularly at their base portions, or to teal# or injure the between substance.

With this object in view one feature ofthe invention consists in thecombination with means for feeding' continuously a doublelipped insole, of Aseparate lip'setting hammers which are moved. Ainto and out of engagement with the inner and outer lips resof construction and arrangements of parts pectively to impart lip setting blows in alter nation thereto. Y,

In the embodiment of the invention herein illustrated the `worlr` feeding lmeans comprises a continuously driven rotary work supporting feed table and a continuously driven hollow feed roll which is mountedabove the feed table and Vco-operates therewith, the feed roll having a periphery adapted to engage the feather of an insole and an end face adapted to engage the material the base of the outer lip of the insole overa `considerable area. AS shown, g the lip turning and setting means comprise a pl iwfor initially raising or turning the outer lip; a horizontally reciprocating movement within Hthe hollowwf'eed roll into engagement with the outer lip abovethe portion engaged by the end face of the feed roll;`

an inner lip turning and setting member movable into andV out of operative engagement with the inner lip; and a vertically re ciprocating lip setting member for engaging fthe outer lip andthe edge portioniof the inner lip, thereby setting the outer `lip and bringing the lips together. Th'eillufstrated Vknife omitted; and for inner lipturning and setting member is arranged to be retractedfrom operativeposition while the outer lip is being acted upon by the horizontally reciprocating outer lip,

turning and setting member, thereby to avoid gripping of the lips between Said members and the resulting interference with the detrated, also, the inner lip turning and set-` ting member is larranged to deliver a blow .against the .inner lip while'tlie horizontally .movable outer lip turning `and setting mem-v ber is inactive and the verticallyniovable lip setting member is arranged to engage the work while theV inner turning and 'setting member ris operative, this arrangement facilitating the setting of the'inner and outer "lips in upstanding positions with their edges inV contact. l The illustrated hollowffeed roll t. is constructed and arranged to form a square Vshoulderattlie base fof the outerV lip,'thus better: fitting the sole to receive'tlie inseam stitches.- D Y Y The invention `further'consists inY features Fig. V3 is -a plan view ofk the operating dcvices' shown in Fig. 2lwith the lip slitting Fig. 4 is a front elevational view of cci'- tain of thejoper'ating instrumentalities.

-The insolelipturning `and setting machine i shown in the drawings is provided witha circular workpsupporting ltable 6V which is rotated continuously about a vertical axis i `during the operation of the machine to feed an insole to andpast the lip `turning andy setting instrumentalities. The table 6 is se `cured to the upper 'end of a spindle `8 journale'd iin suitable bearingsin a frame 1 0. The Y.

table 6 is arranged to be urged upwardly by a spring 12 and to be lowered from work supporting position to facilitate the presentation of the work to the machine and its removal therefrom by means of a treadhle, not shown, which is connected with the spindle 8 by a rod 14.

(lo-operating with the table 6 to feed the worl is a tubular feed roll 16 having a longitudinally grooved or otheiwise roughened exterior surface, the roll being arranged to project over the edge of the table 6 so as to engage the upper side of the feather of a sole on the table. The feed roll 16 is continuouslv rotated during` the operationof the machine about horizontal aXis, the `peripheral speed of the roll and of the table being the same.

The tubular feed roll 16 is formed as the reduced extension of a sleeve 1S which ,is rotatably mounted in the frame 10.` rlhe sleeve 18 has secured to its rear portion a gear 20 which meshes with a gear 22 fast on a horizontal shaft 24 which is mounted in the frame 10 below a horizontal main shaft 26. The main shaft 26 lis provided with a Adriving pulley 28 adapted to be connected with a suitable source of power. Tlieshaft 24 is driven from the main shaft 26 through a two-speed gear `mechanism located within the frame 10aiid indicated conventionally by dotted lines atBO. The table 6 is-driven .from the shaft 24 which, as shown, extends forwaidly beyond the gear-22 and is connected with the table by interineshing `bevel gears 32. The two-speed mechanism 301s arranged to be controlled by the operator through a lever 34 and a treadle rod 36 so that the rate of speed .of the work with relation to the speed of the operating instrumeiitalities .may be varied at the will of the operator. Por example, wien operating Ialong a comparatively straight portion of a sole, .the high speed may be used, and when-operating along the more or less sharply curved portion of the sole, suoli as at the toe, the `slow speed may be used.

For the purpose of opening` the outer'channel and raising the Vouter lip iiito position to be acted upon by the -lip setting instruinentalities, the machine is p royided Witlian outside lip turning tool consisting of a plow 40 ixedlv secured to the frame 10, the .plow being located in front of .the feed -roll 16 and the lip setting devices, i. e., in position to operate upon a portion ofthe. lip .before that portion is eiigagedby the reedroll and acted upon by the lip setting -ineans. As best shown in Fig. 4, one end of the lip turning nlow 40 is located close to the feed roll l16, the end face of the plow being ourvedto correspond with the curvature of the roll. The operative face 42 of the'vplow is shaped te turn upthe outer lip of an insole (such as the lip L of the double-lipped all-leather welt insole `gaging the I,end of a slide 74 (Fig. l)

tical reciprocation in the frame 10. The slide" (4 has formed on its rear face rack teeth S shown in Fig. 2) as the sole is fed through the machine into the path of a horizontal lip turning and setting lianin'ier 44. The plow 40 is adjustably mounted on the frame 10 and may be adjusted vertically to accommodate k securing the plow in any position to which it is moved by the screws 50 and 46.

The lip turning and setting hammer 44 has a curved work engaging end Aface 58 forenouter side of the outer lip L. As shown. the hammer 44 is slidingly mounted coaXially with the feed roll 16 within a bore in the feed roll and the hammer yis rapidly recipiocated to bendvand set the lip L. he hammer 44 is connected at its rear end by a piii-and-.slot connection to one arm of a lever 60 which is Xed on a shaft 62 rotatably mounted in the Aframe 10. Another arm of the lever 60 has vslidingly and rotatably mounted in it a pin 64 which is bored 4transversely of its aXis to receive a crank 66 formed on the inner, end of the main shaft 26. As ,the main shaft 26 rotates, the lever 60 is rocked on itsaXis by the action of thecrank 66 and consequently the hammer 44 is reciprocated within the tubular-feed ioll 16.

o-operating with the horizontally reciprocating hammer 44 inthe setting of theoutcr lip L isa hammer 70 having a curved work engagingface 72 at its lower end. The hammer 70 is adapted to reciprocate vertically .in sliding contact with a vertical end face of the tubular feed roll 16 to engage Vthe lip L after it has been turned inwardly by theliaminer 44 and `to bend the lip downwardly thus completing the setting of the outer lip, the 4.hammer 70 being positioned for this purpose just to one side of the axis of the feed roll 16, as is shown clearly in Figs. 3 and 4. As shown in lthese figures the hammer 70 is so dimeiisioiied that its lower endvopei'ates wholly within a space outlined by a forward projection of the periphery of the feed roll 16. The vertical lip.setting'hamnier Z0 is formed on the lower mounted for verwliich inesh with tlie-teeth of a gear segment 76 formed on a third arin ofthe lever 60, the ari'angeinentebeingsuch that'as the horizontal hammer 44 moves away from the workthe .Vertical hammer 70 moves downwardly -to- Ward the work. In its hammering action 'the vertical hammer 70 bends the llip over and down andbrings theedges of the lips L and Ll together.

For raising the inner lip of a sole, such as the lip L shown in Fig. 2, and opening the inner channel, the illustrated machine is provided with an inside'lipturning'and setting tool having a plowlike portion 81 (Fig. 2)

for entering the channelbeneath the lip. The

tool 80 is provided with a stem 82 (Fig. 1)' which is adjustably clamped in one arm of a lever 84 by a nut 86 threaded on the lower end of the stem 82 and a screw 88 threaded into the stem and engaging the said lever arm. The nut 86 and the screwv 88 enable the tool 8O to be adjusted vertically inV accordance with the thickness of thework and depth of s the inner channel cut, and to be fiXedly scoured in adjusted position. vThe lever 84 is mounted to turn on a shaft 90 mounted in the frame 10 and has an arm 92 which is held by a spring 96 againstan adjustable stop screw 98 carried by the frame. Adjustment of the screw 98 will swing .the lever 84 about the shaft 90 and thus adjust the tool 80 toward or from the plow 40V to accommodate different thicknesses of between substance. The arm 92 of the lever 84 is connected by a link 100 As the horizontal rlip settingrhammer 44 -is moved forwardly to engage the outerv lip L,

the tool 80 is'swung slightly backward against the action of its spring 96 by means of a lug 104 on the lever 60', the lug `104 being arranged to engage a lug106` on the armk 102. This swinging movement of the tool 80 away from the lip L preventsfthe channel lips L and L from being gripped between the hammer 44 and. the tool80 and prevents the feed of the work. which is ^`intended to beY continuous, from being interrupted or retarded'. 1T he fact that the inner lip turning and settingr tool 80 is retracted from the inner lip when the hammer 44 strikes the outer lip `also helps to prevent injury to the between substance. After the outer lip L has been 'disengaged by the hammer 44, the tool 80 is returned by the spring 9 6 into engagement with the inner lip L. This return movement causes a blow to be imparted to the lip L by theltool 80 as the hammer 44 recedes and thisv blow turns up and assists in setting the inner lip. The tool 80 is returned into engagement with. the inner lip in time lto support it against the blow delivererlagainst its upper extremity by the vertical 'hammer 70 and thus assists in setting the inner and outer` lips inf close contact with each other. The connection between the arm 92 vandthe link 100.is ani'eccentric 'pin 1`0`8-b`y means of which Vthe arm 102:inayfbe adjusted about the shaft .62 to vary the space between the lugs 104,4 106 and thereby to vary the amount of movement away from the plow 40 which is to be imparte-d to the tool 80.

The lever 84 h'as'a thirdarm 110 which is connected to the treadle which lowers the work table 6 so that as the tableis lowered the tool 80 is swung away from thefeed roll 16 to permit insertion or removal of work.

To this end,.the arm 110 is connected bya f pin 112 to the upper end of a rod 114 the lower end of which passes through a block 116 and has on its lower end a nut 118 arranged to engage the under side of the block..r The up'- per end of the rod 114 is slotted at 120 to ref ccive the pin 112 and the slot 120 enables the lever 84 to be swung iduring the operation of the machine as vhereinbefore described with- -out affecting the rod'114. j A spring 122 surrounds the rod 114 and at its upper end bears against a head on the rod and' at its lower end against a portion of the frame 10 through which the rod passes. rlhe spring 122 holds the nut 118 up against the block 116 and holds a'lever` 126 by which the block 116 is carried against a stop pin A128 on the frame. The lever 126 is pivoted at 130 to'theframe 10 and extends beneathv a collar 132 on the `table spindle 8 so `that when the work table 6 lis lowered the inner lip turning and setting tool I 80 is swung away from the plow 40.

The abovedescribed arrangement whereby the horizontal hammer 44 operates through the tubular feedwheel 16 prevents thehammer from beating against and tearingA the root of the outer lip and by means of this arrangement` also there is formed at theroot or base of the outer lipV a' square shoulder,

this shoulder being produced by the pressure of the end face of the feed roll 16 against the root of the lip. This square shoulder at the base of the outer lip (which isfindicated at 134 in Fig. 2) provides a surface appropriatelydispose-d to receive' the point ofthe needlein the subsequent welt-sewing, oper-A.

ation.

While the feed ofthe work in the operation of the illustrated machine` hashereinbefore been referred to as continuous., it

should be pointed out that the'distancethc i work travels between each stroke of the lip setting hammers is considerably less than the width of the hammers 44 and 70, being ap- V i proximately /g of an inch, and inasmuch` as the width of the work engaging faces of the hammers is substantially greater th'anthe distance of work travel between successive Vhammer strokes each portion ofthelipV will where the contour of the sole is more or less abruptly curved so as to allow the lips to be readily set perpendicular to the surface of the insole. The knife 140 is clamped to one arm 142 of a 'bell crank lever pivoted at 144 to the frame 10. A second arm 146 of the bell crank lever has slidingly mounted in it ay pin 148 having mounted thereon a cam roll 150 adapted in one position of the pin 148 to be engaged by a cam 152 fixed on the shaft 24. The pin 148 is adapted to be moved axially by means of ahand or treadle lever (not shown) to carry the cam roll 150 into or out of the `path of the cam 152, and thus to render the slitting knife operative or inoperative as may be desired. A spring-pressed plunger 154 suitably mounted in a socket in the frame 10 engages the arm 146 and urges the cam roll 150 either against the cam 152 or against a portion 156 of the frame according .to the axial position of the cam ioll.

In operation, the inner and outer lips of an insole are initially raised by means of the stationaryplow :40 and the tool 8O as the insole is fed continuously past these members, Without interfering with the feed of the work the horizontally reciprocating hammer 44 operates repeatedly upon the outer lip to turn it inwardly beyond the point to which it wasturned by the plow 40 and to exert a preliminary setting action upon the lip. Alternating with the blows of the hammer 44 the blows of the vertically'reciprocating hammer complete the setting of the outer lip. The inner lip turning and setting member 80 is :retractedffrom engagement with the inner lip when the hammer 44 strikes the outer lip thereby preventing the lips from being gripped in such a way as to interfere with the continuous feed of the work. Between successive blows of the hammer 44, however, the tool'SO is caused to strike yielding blows againstthe inner lip, the tool S0 co-operating at these times-with the vertical hammer 70 in the setting of both thefinnerand outer lipsvand insuring that the lips willbe set with their edges in contact.

lVhen operating upon an insole such asa Gem insole in which the edge of theinsole is split and one portion of theedge is turned up at right angles to theface of the insole so that only an outerlip is'forinied, the vertical hammer SOimay be dispensed with and the inner lip turning and setting tool 80 replaced by a'tool havingaiat, smooth, lower face arranged to bear against theroot of the sinele'lip at the side opposite to that 'L engaged by the horizontal hammer 44, this tool operating in the same wayas the tool 80.
